Steering
Steering turns the driver's input into wheel angle and carries feel back to the driver. On WFR26-E it is an evolution of the 2025 system, with a shorter steer arm, a quicker ratio and a steering angle sensor so handling can be measured.

How it works
Steering on WFR26-E prioritises predictability, cornering performance and validation, fixing the shortcomings of the 2025 car rather than starting again.
The geometry was rebuilt around the real operating toe of 1 degree static toe-out and checked in CAD for kinematics and packaging, removing a previous interference and making the anti-Ackermann setting fully usable. That reduced understeer and the minimum turn radius in hairpins and on the skidpad.
Together with GPS and accelerometer data it lets the team compare driver input with what the car actually does.
